What AmSo Compare is
AmSo Compare is a macOS application for comparing, editing, merging, and synchronizing folders and files. It supports three-way and N-way comparison for folders, text files, and binary content, with custom viewers for images and JSON or XML data. Automated N-way merge handles up to eight branches or as many editors as fit on the display. Folder synchronization can merge folders, apply updates, or mirror directory structures. Time Machine backups can be compared, but their data remains read-only. The maker says the app can integrate with popular IDEs and source-control systems such as Git. It runs within the macOS sandbox, where users control permissions, and the App Store listing reports that the developer says it does not collect data. macOS 13.5 or later is required. N-way operations are generally constrained by display area and are unsuitable for small displays. A free trial is available, with subscriptions at $3.99 a month or $12.99 a year, and a 29.99 USD one-time purchase.
